NOTICE:
Raising your vehicle with the jack
improperly positioned will damage
the vehicle or may allow the vehicle
to fall off the jack. Be sure to fit the
jack lift head into the proper
location before raising your vehicle.
11. Raise the vehicle by rotating the
folding wrench clockwise in the
jack. Raise the vehicle far enough
off the ground
so there is enough
room for the spare tire to fit.
12. Remove all the wheel nuts and take
off the
flat tire.
3. Remove any corrosion or dirt from
the wheel bolts, mounting surfaces
or spare wheel. Place the spare on
the wheel mounting surface.

17. Lay the flat tire near the rear of the
vehicle with the valve stem down.
Slide the cable retainer through the
center of the wheel and raise the flat
tire until you hear the hoist
mechanism click twice. This means
the wheel is firmly stored against
the underside of the vehicle. When
storing the spare tire, be certain to
turn the spare
so the valve stem is
near the rear of the vehicle. This
will help you to check and maintain
tire pressure in the spare.
Push against the tire to be certain it
is stored firmly.
18. Replace all jacking tools as they were
stored in the storage compartment and
replace the compartment cover. Be
sure to also store the nylon nut caps.
When
you replace the compact spare
tire with a full-size tire, replace the
nylon nut caps over the wheel nuts.
Tighten them “hand tight” using the
folding wrench (see step
7).
Compact Spare Tire
Although the compact spare was fr .Ill!
inflatedwhen you; vehiile was new, :
can lose air after a time. Check the
jr
it
inflation pressure regularly. It should be
60 psi (420 1tPa). After installing the
compact spare on your vehicle, you
should stop as soon as possible and
make sure your spare tire is correctly
inflated. The compact spare is made to
perform well at posted speed limits for
distances up to
3,000 miles (5 000 ltm).
The compact spare
is made to go up to
3,000 miles (5 000 ltm), so you can
finish your trip and have your full-size
tire repaired
or replaced where you
want. Of course, it’s best to replace
your spare with
a full-size tire as soon
as you can. Your spare will last longer
and be in good shape in case you need it
again.

Loading Your Vehicle
The Certification/Tire label is found on
the rear edge of the driver's door.
The label shows the size
of your original
tires and the inflation pressures needed
to obtain the gross weight capacity
of
your vehicle. This is called the GVWR
(Gross Vehicle Weight Rating). The
GVWR includes the weight of the
vehicle, all occupants, fuel and cargo.
The Certification/Tire label also tells
you the maximum weights for the front
and rear axles, called Gross Axle
Weight Rating (GAWR).
To find out the
actual loads
on your front and rear
axles, you need to go to a weigh station
and weigh your vehicle, Your dealer can help
you with
this. Be sure to spread
out your load equally on both sides
of
the centerline.
Never exceed the
GVWR for your
vehicle, or the Gross Axle Weight
Rating (GAWR) for either the front or
rear axle.
And,
if you do have a heavy load, you
should spread it out.
Electronic Level Control
On vehicles equipped with optional
electronic level control, the rear
of the
vehicle is automatically kept level as
you load or unload your vehicle. For
more about this option see the
Index
under Electronic Level Control.
Using heavier suspension components
to get added durability might not
change your weight ratings. Ask your
dealer to help you load your vehicle the
right way.
NOTICE:
Your warranty does not cover parts
or components that fail because
of
overloading.
If you put things inside your vehicle-
like suitcases, tools, packages, or
anything else-they will go
as fast as
the vehicle goes.
If you have to stop or
turn quickly! or if there is a crash,
they'll keep going.

Inflation-Tire Pressure
The CertificatiodTire label which is on
the rear edge of the driver’s door shows
the correct inflation pressures for your
tires, when they’re cold. “Cold” means
your vehicle has been sitting for at least
three hours or driven no more than a mile.
NOTICE:
Don’t let anyone tell you that
underinflation
or overinflation is all
right. It’s not. If your tires don’t
have enough air (underinflation)
you can get:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air
(overinflation) you can get:
Unusual wear
Bad handling
Rough ride
Needless damage from road
hazards.
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It
should be at
60 psi (420 1tPa).
How to Check
Use a good quality pocket-type gage to
check tire pressure. Simply loolting at
the tires will not tell you the pressure,
especially
if you have radial tires -
which may look properly inflated even if
they’re underinflated.
If your tires have valve caps, be sure to
put them back on. They help prevent
leaks by keeping out dirt and moisture.

Tire Inspection and Rotation
To make your tires last longer, have
them inspected and rotated at the
mileages recommended in the
Maintenance Schedule. See
Scheduled
Maintenance Services
in the Index.
Use this rotation pattern.
After the tires have been rotated, adjust
the front and rear inflation pressure as
shown on the CertificationlTire label.
Make certain that all wheel nuts are
properly tightened. See
Wheel Nut
Toque in the Index.

Uniform Tire Quality Grading
The following information relates to the
system developed by the United States
National Highway Traffic Safety
Administration which grades tires by
treadwear, traction and temperature
performance. (This applies only to
vehicles sold in the United States.)
Treadwear
The treadwear grade is a comparative
rating based on the wear rate
of the tire
when tested under controlled conditions
on a specified government
test course. For example, a tire graded
150 would wear one and a half (1 %)
times as well on the government course
as a tire graded
100. The relative
performance of tires depends upon the
actual conditions of their use, however,
and may depart significantly from the
norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.
Traction-A, B, C
The traction grades, from highest to
lowest are:
A, B, and C. They represent
the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete.
A tire
marked
C may have poor traction
performance.
Warning: The traction grade assigned to
this tire is based on braking (straight-
ahead) traction tests and does not
include cornering (turning) traction.
Temperature-A, B, C
The temperature grades are A (the
highest)
B, and C, representing the
tire’s resistance to the generation of heat and its
ability to dissipate heat
when tested under controlled
conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material
of
the tire to degenerate and reduce tire
life, and excessive temperature can lead
to sudden tire failure. The grade
C
corresponds to a level of performance
which all passenger car tires must meet
under the Federal Motor Vehicle Safety
Standard
No. 109. Grades B and A
represent higher levels of performance
on the laboratory test wheel than the
minimum required by law.
Warning: The temperature grade for
this tire is established for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or in
combination, can cause heat buildup
and possible tire failure.
These grades are molded
on the
sidewalls of passenger car tires.
While the tires available as standard or
optional equipment on General Motors
vehicles may vary with respect to these
grades, all such tires meet General
Motors performance standards and

Introduction
A Word About Maintenance
We at General Motors want to help you
keep your vehicle in good working
condition. But we don’t lmow exactly
how you’ll drive it. You may drive very
short distances only a few times a week.
Or you may drive long distances all the
time in very hot, dusty weather.
You
may use your vehicle in malting
deliveries. Or
you may drive it to work,
to do errands or in many other ways.
Because of all the different ways people
use their GM vehicles, maintenance
needs vary.
You may even need more
frequent checks and replacements than
you will find in the schedules in this
part.
So please read this part and note
how you drive. If you have any
questions on how to keep your vehicle
in good condition, see your Oldsmobile
dealer, the place many GM owners
choose to have their maintenance work
done. Your dealer can be relied upon to
use proper parts and practices.
Your Vehicle and the Environment
Proper vehicle maintenance not only
helps to keep your vehicle in good
working condition, but also helps the
environment. All recommended
maintenance procedures are important. Improper vehicle maintenance or the
removal of important components can
significantly affect the quality
of the air
we breathe. Improper fluid levels or
even the wrong tire inflation can
increase the level of emissions from
your vehicle.
To help protect our
environment, and to help keep your
vehicle in good condition, please
maintain your vehicle properly.
How This Part is Organized
The remainder of this part is divided
into five sections:
Section
A: Scheduled Maintenance
Services shows what to have done and
how often. Some of these services can
be complex,
so unless you are technically
qualified and have the necessary
equipment, you should let your dealer’s
service department or another qualified
service center do these jobs. If
you are skulled enough to do some
work on your vehicle, you will probably
want to get the service information GM
publishes. You will find a list of
publications and how to get them in
this manual. See
Service Publications
in the Index.
Section B: Owner Checks and Services
tells you what should be checked
whenever you stop for fuel. It also
explains what you can easily do to help
keep your vehicle in good condition.
